Assessing the impact of background subtraction on a dust-free corona

Erika Palmerio, Cooper Downs, Phillip Hess +4

Context. White-light observations of the solar corona contain contributions from both the electron-scattered K-corona and the dust-scattered F-corona. Because the diffuse F-corona…

Portability of Fortran's 'do concurrent' on GPUs II

Ronald M. Caplan, Miko M. Stulajter, Jon A. Linker +6

There continues to be growing interest in using standard language constructs for parallel and accelerated HPC computing, avoiding the need for (sometimes vendor-specific) external…

Quantifying Uncertainties in Solar Wind Forecasting Due to Incomplete Solar Magnetic Field Information

Stephan G. Heinemann, Jens Pomoell, Ronald M. Caplan +5

Solar wind forecasting plays a crucial role in space weather prediction, yet significant uncertainties persist due to incomplete magnetic field observations of the Sun. Isolating t…

Open-source Flux Transport (OFT). I. HipFT -- High-performance Flux Transport

Ronald M. Caplan, Miko M. Stulajter, Jon A. Linker +6

Global solar photospheric magnetic maps play a critical role in solar and heliospheric physics research. Routine magnetograph measurements of the field occur only along the Sun-Ear…

Advancing parabolic operators in thermodynamic MHD models II: Evaluating a Practical Time Step Limit for Unconditionally Stable Methods

Ronald M. Caplan, Craig D. Johnston, Lars K. S. Daldoff +1

Unconditionally stable time stepping schemes are useful and often practically necessary for advancing parabolic operators in multi-scale systems. However, serious accuracy problems…
